text: To make this kind of race possible, a considerable number of problems had to be solved beforehand, such as the choice of the track and its preparation, the improvement of monitoring and control devices, in particular the sensitivity of current measurements, the evaporation of a large number of very different molecules on the same surface and microscope validation
  Among the benefits, the CNRS cites the development molecular motors and Tech-Atoms, that will make possible in the future the preparation of quantum electronic circuits on the surface of an insulator, atom by atom, whose calculating parts will measure less than 1 nm.
